3560 boot failure

I have a 3560-24PS switch that began constantly rebooting this morning and I'm unable to get it to stop.  Here's an output of what it's doing:

Is this fixable?

Any assistance is appreciated.

Re: 3560 boot failure

The switch is in a state called a boot-n-crash loop.  In this state, the switch boots up, encounters a problem, creates a crashlog info file/subdirectory, reboots and repeats the cycle.  Now somewhere during the process, the issue was "rectified" but  the flash memory is full and the switch couldn't write any updates of the crashlog so it crashes once more.

What you need to do is to power off the switch for about 10-15 seconds.  Power it up.  If the power comes back up, you need to delete the crashinfo subdirectory (command:  delete /f  /r flash:).

Hope this helps.  Please don't forget to rate our posts.

Re: 3560 boot failure

Hi Rob,

I tried to check the issue and i can see that the switch is reloading while it is running. i decoded the tracebacks for you and found 4 bugs whic are hitting the image which you are using. I cannot share the bug id's with you as they are internal and confidential to Cisco.


That tells us to upgrade the switch to the latest version to fix the issue.
